What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Anchorage, AK wrote its last area forecast discussion before this small craft advisory went out at Dec 23, 5:22 AM AKST, 9 hours 47 minutes earlier.

Area forecast discussion, Dec 23, 5:22 AM AKST, 9 hours 47 minutes before

Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
522 AM AKST Sat Dec 23 2017

.ANALYSIS AND UPPER LEVELS...
The overhead longwave pattern is fully established with a blocking
high firmly entrenched over the ALCan border. The active east
Asian jet, protruding well into the northern Pacific, is buckling
in response, creating a very high amplitude pattern. The upper low
over Kamchatka isn't overly strong with most of the action
associated with the jet to the south. Deep layer southeast flow
still exists from the western Gulf of Alaska through the southwest
Mainland. While the High Wind Warning has expired over the
Bristol Bay area, gusty winds remain. A stalled frontal boundary
sits over the far end of the Alaska Peninsula where Cold Bay has
seen 12.9 inches of accumulating snow overnight.

&&

.MODEL DISCUSSION...
Guidance are in great agreement with the progression of the Alaska
Peninsula surface low center for the next couple days as well as
the exiting of the upper level trough inland.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The front which has been nearly stationary over the southwest
Gulf, will begin to make some northward progress beginning later
today as the upper level trough over the northeast Pacific begins
to lift. However, with a strong blocking ridge along the ALCAN
border the trough will stall as it nears Southcentral, with the
surface front elongating and weakening. The latest forecast
continues to trend slower with the frontal progression and
confines most of the precipitation to the immediate Gulf coast,
namely the southern to eastern Kenai Peninsula. Thus, most of
Southcentral will remain dry through the weekend. Forecast
confidence drops as we head into Christmas Day, with a weak
remnant trough trying to move over Southcentral. This means
there is some potential for flurries or light snow, but nothing
organized that would produce much (if any) accumulation.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...
Very little change in the weather is expected today as persistent
southeasterly winds and cloudcover will keep temperatures well
above normal with rainfall confined to the delta coast and
easterly facing terrain. This pattern will begin to break down
late tonight as the low south of the AK pen continues to weaken,
allowing the pressure gradient to begin to slacken by Sunday
morning. This will allow temperatures to slowly fall back below
freezing with diminishing winds, and just an outside chance of a
passing light rain/snow shower through Monday.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...
The biggest concern today will be for the potential for snow and
blowing snow east of the Prib's today as the weakening trough
currently over the Eastern Bering is quickly replaced by another
that will develop this afternoon. As was observed with the heavy
snow in Cold Bay yesterday under a similar sharp trough, the
heaviest of the snow should occur along the AK pen, where up to
10 inches of new snowfall should occur, likely to the east of Cold
Bay this time. Along with the snow, gale force northerly winds
behind the trough is expected to bring areas of blowing snow,
especially to the AK pen that already saw a round of snowfall
yesterday. As a result of this a winter weather advisory was
issued through tonight for snow and blowing snow concerns.
Further to the west over the Eastern Aleutians/Prib's the snowfall
should be much lighter and showery. This low is then expected to
move eastward and weaken below gale force on Sunday, leaving much
of the area under the influence of a slowly moving low complex
into Monday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Beginning the extended period forecast Sunday evening, there will
be a weakening upper trough lifting northward along the Gulf Coast
with a highly amplified upper ridge over the eastern part of
Alaska. Weak upper troughing will extend over Southwest Alaska and
the Bering Sea. Rain and snow along the Gulf Coast and over Kodiak
will continue but slowly diminish through Tuesday as the trough
moves inland and falls apart. By that time, high latitude
blocking in the vicinity of Eastern Siberia and the Beaufort Sea
will begin to exert a stronger influence on the pattern, and as
usual, this lends to lower confidence and higher variability with
the upper level wave pattern after Thursday. With that said,
surface high pressure will effectively "block" the storm track
away from Alaska and the Bering Sea, so the weather pattern looks
rather quiet and banal with seasonable temperatures and what looks
to be dry offshore flow for most of Southern Alaska by Tue-Thu.
